Upper coolant hose: 72.222
Lower coolant hose: 58.8
Radiator reservoir cap: 62
Cylinder 1 head: 82.2
Cylinder 3 head: 94.4
On radiator: 84.4
So, any ideas? Is my temp gauge off? It is important to mention I saw some relief pressure coming from the overflow cap, indicating it is actually that hot.
Will investigate some more, and get the oil analysis before I start dumping money in it. I know this can be characteristic of the 603, but is a bit extreme.

Squeeze the upper radiator hose after the car has cooled down over night. It should not be holding pressure. Have you cleaned the outside of the condenser? The air has to flow through it to reach the radiator.
